The invention discloses a node B WTRU supporting DC-HSDPA and a method used in the node B WTRU. The WTRU comprises a receiver which is configured to receive a high speed shared control channel (HS-SCCH) order through at least one of an anchor carrier and a supplementary carrier, wherein the HS-SCCH order is used for activating discontinuous reception (DRX); and a controller which is configured to respond to that the HS-SCCH order activate the DRX upon the anchor carrier and the supplementary carrier.
Description
The application is that application number is 200980114683.0, the applying date is on 04 24th, 2009, is entitled as the dividing an application of Chinese patent application of " for receive and carry out the method and apparatus of discontinuous transmission and reception in the access of double small district high-speed downlink packet on two carrier waves simultaneously ".
Technical field
The application relates to radio communication.
Background technology
Third generation partner program (3GPP) standard is constantly development.Early stage version mainly concentrates in voice communication, and how nearest version has been placed on attentiveness data communication service, in high-speed packet access (HSPA).The continual exploitation of grouping access service is by mobile subscriber at any time, from being connected to Anywhere internet, to carry out the demand of amusement, commercial affairs or other objects, promote.
In version 7, introduced continuous grouping and connected (CPC) as far as possible for a long time device is remained in IA High Speed Channel (, in active state), simultaneously by reduce the counter productive of maintenance activity during low periods of activity, and do not carry out data transmission (that is, reduce power consumption within that time and reduce the bandwidth demand of radio layer signaling).The feature realizing together with CPC in these features is discontinuous transmission (DTX) and discontinuous reception (DRX).DTX pattern and DRX pattern and the rule group permission wireless transmission/reception unit (WTRU) being associated are closed its transmitter and receiver to save power supply during low periods of activity.
Up link DTX is how a kind of definition WTRU will transmit the mechanism of Dedicated Physical Control Channel (DPCCH) discontinuously.Up link DTX is configured by radio network controller (RNC).Up link DPCCH burst mode and up link DPCCH preamble and postamble jointly define discontinuous up link DPCCH operation.Up link DTX depends on enhancement type special channel (E-DCH) and High-Speed Dedicated Physical Control Channel (HS-DPCCH) activity.Can collocating uplink link DTX and do not need configuring downlink DRX.
Fig. 1 illustrates the DPCCH burst mode for up link.Two DTX patterns (UE_DTX_cycle_1 (UE_DTX_ circulation _ 1) and UE_DTX_cycle_2 (UE_DTX_ circulation _ 2)) are defined for WTRU and carry out discontinuous up link DPCCH operation.Application UE_DTX_cycle_1 or E_DTX_cycle_2 depend on the duration of E-DCH inactivity.When the E-DCH of the subframe less than for predetermined number transmission, use UE_DTX_cycle_2.Therefore, DPCCH transmission rate automatically adapts with data transfer activities.For example, during higher data transfer activities, this up link DPCCH can be configured to transmit more continually, and during lower data transfer activities, this DPCCH can be configured to often not transmit to produce DTX gain.For providing the DPCCH burst mode of the different WTRU of service to be offset by Node B, make different WTRU at its DTX separately, in the cycle, to there is its DPCCH transmission phase place in different periods.
As long as when E-DCH or HS-DPCCH are transmitted, DPCCH is just transmitted.When WTRU is not during at E-DCH or HS-DPCCH transmitting data, except each UE_DTX_cycle_1 subframe (subframe 107,109,111 ...) outside the upper short burst that transmits a subframe, WTRU does not transmit DPCCH.During last Inactivity_Threshold_for_UE_DTX_cycle_2 (for the inertia thresholding of UE_DTX_cycle_2) subframe (last E-DCH frame 101), if WTRU does not transmit E-DCH, except each UE_DTX_cycle_2 subframe (subframe 113 ...) outside the upper short burst that transmits a subframe, this WTRU does not transmit DPCCH.
Introduced double small district high-speed downlink packet access (DC-HSDPA) pattern, wherein two HSDPA carrier waves are used for downlink transmission to improve the throughput of each community.In DC-HSDPA pattern, Yi Ge community is covered by maximum two the HSDPA carrier waves (contiguous carrier wave as much as possible) in identical frequency band.Frequency diversity between carrier wave can provide gain.DC-HSDPA provides the throughput of increase and the stand-by period of minimizing.Under poor radio condition, other technology, may be unpractical, and DC-HSDPA allows more UE to be linked into higher data rate such as multiple-input and multiple-output (MIMO).At network side, except some capacity gain, DC-HSDPA allows effective load balancing on carrier wave.WTRU can be configured to carry out DC-HSDPA operation under CELL_DCH state.
DTX and DRX operation define the operation for single carrier wave clearly, and the current mechanism of processing DRX operation under DC-HSDPA pattern that do not exist.In addition,, in the situation that HS-SCCH only transmits a carrier wave in described carrier wave, the current indication WTRU that do not exist transmits the mechanism of the HS-PDSCH being associated on which carrier wave.
Summary of the invention
Disclose a kind of for receive and carry out at DC-HSDPA the method and apparatus of DTX and DRX on two carrier waves simultaneously.WTRU receives at least one the message of DRX be used for activating anchor carrier and auxiliary (supplementary) carrier wave, once and receive this message, just by same DRX model application in anchor carrier and subcarrier.Described message can be received via HS-SCCH order.If data receive via any one in anchor carrier and subcarrier, described WTRU can all carry out deexcitation (de-activate) DRX on anchor carrier and subcarrier.Alternatively, only in data while being received via subcarrier, described WTRU can carry out the deexcitation of DRX on subcarrier.
Described WTRU can be based on physical layer signal, and such as HS-SCCH, order activates described subcarrier or carries out the deexcitation to described subcarrier.Once the inactivity timer for subcarrier expires, described WTRU can carry out deexcitation to subcarrier.Once activation subcarrier, described WTRU can be by same DRX model application in anchor carrier and subcarrier.Once described subcarrier has been carried out to deexcitation, described WTRU just can refresh mixed automatic repeat request (HARQ) buffer being associated with subcarrier.Alternatively, after reactivating described subcarrier, described WTRU can be using the data that receive via subcarrier as new data processing.

Fig. 2 shows an example wireless communication system 200, this wireless communication system 200 comprises node-b 220, controls radio network controller (CRNC) 230, service radio network controller (SRNC) 240, core network 250 and a plurality of WTRU210.This WTRU210 communicates by letter with Node B 220, and Node B 220 is communicated by letter with SRNC240 with CRNC230.This CRNC230 and SRNC240 can be identical entities.Node B 220 and WTRU210 have DC-HSDPA ability, and can carry out sending and receiving down link data via two carrier waves.
Fig. 3 is the block diagram of example WTRU210 and example endpoint-B220.This WTRU210 communicates by letter with node-b 220, and is both configured to carry out DTX and DRX with DC-HSDPA pattern.This WTRU210 comprises controller 215, receiver 216, transmitter 217 and antenna 218.This controller 215 is configured to DC-HSDPA pattern, carry out DRX and DTX operation according to the execution mode control receiver 216 of following discloses and transmitter 217.Node B 220 comprises controller 225, receiver 226, transmitter 227 and antenna 228.This controller 225 is configured to DC-HSDPA pattern, carry out DRX and DTX operation according to the execution mode control receiver 226 of following discloses and transmitter 227.
Node-b 220 can send data to WTRU210 via anchor carrier and subcarrier simultaneously, and this WTRU210 can receive data simultaneously on anchor carrier and subcarrier.This anchor carrier and subcarrier can be worked in identical frequency band.This anchor carrier and subcarrier can have identical time reference, and its down link can be by synchronously.
When DC-HSDPA operation is activated, WTRU210 can receive data by any one carrier wave from two downlink carriers.If WTRU210 is configured to side by side monitor HS-SCCH on two carrier waves, taking to set up subcarrier into account new DRX pattern will be useful.For the DRX pattern of anchor carrier (or equivalently HS-SCCH receiving mode), can follow the normal mode of current execution.The execution mode of the DRX pattern of following discloses configuration subcarrier.
According to the first execution mode, for the DRX pattern of grappling community and assisted cell, be aligned.WTRU HS-SCCH receiving mode for subcarrier accurately aligns with the HS-SCCH receiving mode of anchor carrier.This allows WTRU on two carrier waves, to monitor HS-SCCH simultaneously, and saves battery supply according to WTRU hardware implementation mode and configuration.In addition, this will allow network only to indicate a DRX pattern, and this DRX pattern will be applied to grappling community and assisted cell.
Selectively, if there is auxiliary uplink carrier, the DTX pattern of grappling uplink carrier and auxiliary uplink carrier can be aligned.Described network only sends with signal a DTX pattern that is applied to two uplink carriers.
Can be from grappling community or assisted cell via HS-SCCH order (, DRX activation/deactivation bit in HS-SCCH order) with signal, send the initiation (or activation and deexcitation) of DRX and/or DTX pattern, and be implicitly applied to Liang Ge community.Alternatively, can transmit HS-SCCH order via each community, to control independently the DRX (and/or DTX) of each community.
According to the first execution mode, for the HS-SCCH receiving mode of two carrier waves, can be defined as one group of subframe, HS-SCCH DRX radio frame numbering CFN_DRX of this group subframe and subframe numbering S_DRX meet following equation:
((5*CFN_DRX-UE_DTX_DRX_Offset+S_DRX)MOD?UE_DRX_cycle)＝0；
Equation (1)
Wherein UE_DTX_DRX_Offset is up link DPCCH burst mode and the skew of HS-SCCH receiving mode in subframe, and UE_DRX_cycle is the HS-SCCH receiving mode length in subframe.
Fig. 4 shows the DRX pattern of alignment of the 2ms Transmission Time Interval (TTI) of UE_DRX_cycle=4.Multirow 403 at top shows the DRX pattern on grappling community, and the multirow 405 of bottom shows the DRX pattern on assisted cell.DRX pattern for grappling community and assisted cell is aligned, and makes WTRU monitor HS-SCCH on subframe 407 and 409, and can on subframe 411 and 413, receive HS-PDSCH simultaneously.
In addition, if WTRU is not configured to monitor any HS-SCCH on subcarrier, during the TTI at this WTRU expectation HS-PDSCH (as what the HS-SCCH by sending in anchor carrier was indicated), can allow this WTRU not intercept subcarrier (that is, constant DRX).
According to the second execution mode, for the WTRU DRX pattern of subcarrier, be displaced to the DRX pattern of anchor carrier.This skew is pre-defined or is configured by network.In any situation in both of these case, for the HS-SCCH receiving mode of anchor carrier, can be defined as one group of subframe, HS-SCCH DRX radio frame numbering CFN_DRX of this group subframe and subframe numbering S_DRX checking (verify) following equation:
((5xCFN_DRX-UE_DTX_DRX_Offset+S_DRX)MOD?UE_DRX_cycle)＝0；
Equation (2)
HS-SCCH receiving mode for subcarrier can be defined as one group of subframe, the discontinuous reception radio of the HS-SCCH DRX frame number CFN_DRX of this group subframe and the following equation of subframe numbers S_DRX checking:
((5*CFN_DRX-UE_DTX_DRX_Qffset+SUPPC_OFFSET+S_DRX) MODUE_DRX_cycle)=0; Equation (3)
Wherein SUPPC_OFFSET is the skew to the HS-SCCH receiving mode for anchor carrier for the HS-SCCH receiving mode of subcarrier.SUPPC_OFFSET can be pre-defined or be configured by network.SUPPC_OFFSET value can be one (1), and in this case, for the DRX pattern of grappling and subcarrier, is staggered.Alternatively, SUPPC_OFFSET can be set to floor (UE_DRX_cycle/2), in this case, for the DRX pattern of grappling and subcarrier, hockets.
When Fig. 5 shows UE_DRX_cycle=4 and SUPPC_OFFSET=1 for the skew DRX pattern of 2ms TTI.The multirow 503 at top shows the DRX pattern on grappling community, and the multirow 505 of bottom shows the DRX pattern on assisted cell.DRX pattern for grappling community and assisted cell is staggered, and makes WTRU monitor HS-SCCH on subframe 507 and 509, and can on subframe 511 and 513, receive HS-PDSCH.
This WTRU DTX cycle can only align with the DRX cycle of anchor carrier or subcarrier.Alternatively, this WTRU DTX cycle can align with the DRX cycle of grappling and subcarrier.Alternatively, when on one or two downlink carriers when continuous reception (CRX), this WTRU can be always in continuous transmission (CTX).
Can with signal, send via the HS-SCCH order from grappling community or assisted cell the initiation of DRX and/or DTX pattern, and implicitly be applicable to Liang Ge community.Alternatively, can activate independently DRX and/or DTX for each community, the HS-SCCH order that for example can stem from each community by use is for activating independently DRX and/or DTX in each community.
The DRX pattern of anchor carrier and subcarrier can configure independently, and in kind of situation, different independently DRX cycles can be applied to different downlink carriers.In this case, can activate independently or jointly and this DRX of deexcitation for each community.
In addition, if WTRU is not configured to monitor any HS-SCCH on subcarrier, during the TTI at this WTRU expectation HS-PDSCH (as indicated by the HS-SCCH sending in anchor carrier)), can allow this WTRU not intercept subcarrier (that is, constant DRX).
According to the 3rd execution mode, WTRU carrys out its receiving mode preference of indication network via high-level signaling more.According to the carrier spacing, different WTRU execution modes can have benefited from different DRX patterns.For example, this WTRU can be via high-level signaling more and send with lower one with signal:
(1) the DRX pattern of the alignment between the preferred carrier wave of this WTRU;
(2) the staggered DRX pattern between the preferred carrier wave of this WTRU; Or
(3) any one in described other DRX patterns disclosed here.
This WTRU also can indicate its preferred SUPPC_OFFSET value via RRC signaling to network.Thereby this network is configured for the WTRU DRX pattern of subcarrier subsequently.This network may not meet the request of WTRU.Alternatively, this WTRU can suppose the DRX pattern that network is used WTRU to ask always.
In addition, if WTRU is not configured to monitor any HS-SCCH on subcarrier, during the TTI at this WTRU expectation HS-PDSCH (as HS-SCCH indication by sending in anchor carrier)), can allow this WTRU not intercept subcarrier (that is, constant DRX).
According to the 4th execution mode, for the WTRU DRX pattern of subcarrier, can there is the cycle different from the DRX pattern of anchor carrier.The DRX pattern cycle of this subcarrier can be the integral multiple of anchor carrier DRX pattern cycle.Multiplication constant can be pre-defined or be sent with signal by network.
If multiplication constant is M, the HS-SCCH receiving mode for subcarrier can be defined as one group of subframe, and the HS-SCCH DRX radio frame numbering CFN_DRX of this group subframe and subframe numbering S_DRX meet following equation:
((5xCFN_DRX-UE_DTX_DRX_Offset+S_DRX)MOD(MxUE_DRX_cycle)＝0.
Equation (4)
For example, this multiplication constant can be two (2).In this case, the HS-SCCH receiving mode for subcarrier can be defined as one group of subframe, the HS-SCCH DRX radio frame numbering CFN_DRX of this group subframe and the following equation of subframe numbering S_DRX checking:
((5xCFN_DRX-UE_DTX_DRX_Offset+S_DRX)MOD(2xUE_DRX_cycle))＝0.
Equation (5)
The binary cycle DRX pattern of 2ms TTI when Fig. 6 shows UE_DRX_cycle=2 and M=2, the DRX cycle of assisted cell is accurately two double-lengths of the DRX cycle of grappling community here.The multirow 601 at top is illustrated in the DRX pattern on grappling community, and the multirow 603 of bottom is illustrated in the DRX pattern on assisted cell.The DRX cycle of this assisted cell is DRX cycle two double-lengths of grappling community, makes WTRU monitor HS-SCCH in the subframe 605 of grappling community and in the subframe 609 of assisted cell, and can on subframe 607 and 611, receive HS-PDSCH respectively.
The DRX cycle that is applied to subcarrier and anchor carrier can be identical.Alternatively, can apply different independently DRX cycles, or can be the integral multiple of anchor carrier DRX cycle for the DRX cycle of subcarrier.The exploitation of this DRX cycle plays with the DRX cycle of grappling community align (fully align or align with the integral multiple of above-mentioned DRX cycle), but the duration can be different.Alternatively, the DRX cycle of this anchor carrier can be the integral multiple of the DRX cycle of subcarrier.
This WTRU DTX pattern can be alignd with the overlay segment of grappling and auxiliary DRX cycle.This fully closes radio by permission WTRU in all carrier waves and up link and both downlink, thereby optimizes battery life.Alternatively, this DTX cycle can align with the DRX cycle of grappling community or assisted cell.
Following discloses are for DRX and/or the activation of DTX and the execution mode of deexcitation.When data are received on subcarrier, this WTRU departs from DRX, thereby on the cycle, intercepts follow-up HS-SCCH at Inactivity_Threshold_for_UE_DRX_cycle.Under the background of double small district HSDPA, can in any one of two downlink carriers, receive HS-SCCH.In the following description, transfer of data can, including, but not limited to HS-SCCH and HS-PDSCH, still can not be used as fractional dedicated physical channel (F-DPCH) and HS-SCCH order as transfer of data.
According to an execution mode, DRX activation and deactivation process are fully independent on each downlink carrier.If receive data on subcarrier, this WTRU monitors the subcarrier for HS-SCCH (or HS-PDSCH) on the pre-configured time period.If do not receive data on WTRU, the DRX pattern in anchor carrier can be held so.If receive data in anchor carrier, apply identical scheme.
After Fig. 7 shows and receive data in anchor carrier, the example DRX deexcitation in anchor carrier.In the example of Fig. 7, for the DRX pattern of anchor carrier and subcarrier, align with 2ms TTI and UE_DRX_cycle=4.The multirow 701 and 702 at top is respectively the Node B transmission on grappling community and assisted cell.The multirow 703 and 704 of bottom shows respectively the DRX pattern of the WTRU on grappling community and assisted cell.This WTRU according to configured DRX pattern grappling and subcarrier 707 and 709 on intercept HS-SCCH.This Node B transmits HS-SCCH via grappling community on subframe 705 and 706.Once WTRU receives HS-SCCH in subframe 705, this WTRU just carries out the deexcitation of DRX on grappling community, and transmission 706 last from grappling community starts, on grappling community, start to monitor Inactivity_Threshold_for_UE_DRX_cycle subframe (that is, subframe 708).This WTRU monitors HS-SCCH (that is, monitoring subframe 709) according to normal DRX pattern on assisted cell.
Alternatively, the DRX pattern of anchor carrier and subcarrier can link together.Fig. 8 shows according to this replaceable execution mode, receives the example DRX deexcitation after data in anchor carrier.In the example of Fig. 8, for the DRX pattern of anchor carrier and subcarrier, align with 2ms TTI and UE_DRX_cycle=4.The multirow 801 and 802 at top is respectively the Node B transmission on grappling community and assisted cell.The multirow 803 and 804 of bottom shows respectively the DRX pattern of the WTRU on grappling community and assisted cell.This WTRU according to configured DRX pattern grappling and subcarrier 807 and 809 on intercept HS-SCCH.This Node B transmits HS-SCCH via grappling community on subframe 805 and 806.Once WTRU receives HS-SCCH in subframe 805, this WTRU just carries out the deexcitation of DRX on grappling community and assisted cell, and transmission 806 last from grappling community starts, on grappling community and assisted cell, start to monitor Inactivity_Threshold_for_UE_DRX_cycle subframe (that is, subframe 808 and 810).
Alternatively, when receiving data on subcarrier, this WTRU monitors the auxiliary and anchor carrier for HS-SCCH and/or HS-PDSCH during Inactivity_Threshold_for_UE_DRX_cycle, but when WTRU receives data in anchor carrier, can on subcarrier, maintain DRX.
Can configure these different mechanism by network utilisation L3 signaling, or pre-defined in WTRU.
The execution mode of HS-PDSCH carrier wave indication has hereinafter been described.The in the situation that a carrier wave in two carrier waves only transmitting HS-SCCH (being preferably, in anchor carrier), need to provide an additional indication, to show the intercepting HS-PDSCH being associated on which carrier wave.Should be noted that, execution mode as described below can be applicable to the HS-SCCH scheduling of transfer of data on HS-PDSCH or HS-SCCH order, wherein decoding its on HS-SCCH HS-DSCH radio net temporary mark (H-RNTI) afterwards, this WTRU does not need to monitor HS-PDSCH again.
According to an execution mode, WTRU need to be used for monitoring that the carrier wave of HS-PDSCH or HS-SCCH is directly linked to HS-SCCH channel code.This can realize by increase the information element (IE) of an indication carrier wave (anchor carrier or subcarrier) in HS-SCCH Info (information) information element (IE) defining in 3GPP TS25.331V.8.5.0 part 10.3.6.36a.For example, as shown in table 1, new row can be added to HS-SCCH Info IE.For representing that the Xiang Biao newly increasing 1 of downlink carrier has added underscore.
Table 1
Alternatively, give different H-RNTI of each allocation of carriers (for anchor carrier, and another is for subcarrier).This WTRU monitors the HS-SCCH of two H-RNTI.If the H-RNTI of the anchor carrier of decoding on HS-SCCH, this WTRU knows that this scheduling can be applicable to anchor carrier, and if the H-RNTI of the subcarrier of decoding on HS-SCCH, this WTRU knows that this scheduling can be applicable to subcarrier.
Alternatively, can be in the HS-SCCH being associated explicitly indication for the carrier wave of the HS-PDSCH that is associated.Because needing this information, this WTRU starts buffer memory HS-PDSCH, so must carry this carrier information in the first of HS-SCCH.This carrier wave represents bit X
cican be included the part that bit is set as channel code conventional in HS-SCCH.This can realize by reducing channel code dispatching flexibility, and this process be take carrier wave flexibility as cost.Be disposed for the channelization code that the WTRU of DC-HSDPA operation automatically reinterprets HS-SCCH by the definition according to new bit is set, to determine the number of carrier wave indication, channel code skew and HS-PDSCH code in the transfer of data being associated.
Alternatively, can define new HS-SCCH type, wherein first comprises the extra order for carrier wave indication.For example, when WTRU is not configured for MIMO operation, new HS-SCCH type can comprise following information in its part 1:
-channel code configuration information (7 bits): x
ccs, 1, x
ccs, 2..., X
ccs, 7;
-modulation scheme information (1 bit): x
ms, 1;
-carrier wave indication information (1 bit): x
ci.
Similarly, when WTRU is configured for MIMO operation, new HS-SCCH type can comprise following information in its part 1:
-channel code configuration information (7 bits): x
ccs, 1, x
ccs, 2..., X
ccs, 7;
-transport module number and modulation scheme information (3 bits): x
ms, 1, x
ms, 2, x
ms, 3;
-precoding weight information (2 bits): x
pwipb, 1, x
pwipb, 2;
-carrier wave indication information (1 bit): x
ci.
For example, this carrier wave indication bit can be defined, thereby makes to work as x
ci=0 o'clock, in anchor carrier, send the HS-PDSCH being associated, otherwise on subcarrier, send the HS-PDSCH being associated.For two kinds of situations, by defining simply new parameters of rate matching, reusing similar chnnel coding mechanism is possible as a kind of normal channel encoding mechanism for HS-SCCH part 1.
According to another execution mode, this WTRU determine whether timing (timing) that HS-SCCH based on anchor carrier or subcarrier receives and in anchor carrier or on subcarrier decoded data.
In the situation that staggered DRX pattern is for grappling and subcarrier, this indication naturally based on for determining whether WTRU should attempt the identical criterion (rule) of reception on a carrier wave of a plurality of carrier waves.This means if anchor carrier according to DRX pattern, may receive anchor carrier time engrave and be received, HS-SCCH points to anchor carrier, and if subcarrier according to DRX pattern, may receive subcarrier time engrave and be received, HS-SCCH points to subcarrier.In any situation in two kinds of situations, can in anchor carrier or on subcarrier, transmit HS-SCCH, but not have explicit indication to show which carrier wave that should intercept must provide in HSSCCH itself.
Alternatively, can there is a kind of different pattern for receive HS-PDSCH on anchor carrier or subcarrier.For example, if HS-SCCH receives in one group of subframe, this WTRU HS-PDSCH that can decode in anchor carrier, the radio frame numbering CFN_Anchor of wherein said one group of subframe and subframe numbering S_Anchor meet following equation:
((5*CFN_Anchor-Anchor_Offset+S_Anchor) MOD2)=0. equation (6)
This WTRU HS-PDSCH that decodes on subcarrier in all other subframes.
If with signal downlink carrier decode HS-PDSCH execution mode and use staggered DRX pattern, this WTRU may be to start receiving HS-SCCH among two continuous TTI from subframe, and this subframe is defined by the DRX receiving mode of one of two kinds of carrier waves.
Following discloses are for the execution mode of quick subcarrier activation and deexcitation.The activation of this subcarrier and deexcitation are by carrying out by L1 or L2 signaling.
According to an execution mode, this network transmits a L1 signal to indicate it to be applied to subcarrier by receiving continuously (effectively carrying out the deexcitation of DRX) to WTRU.This can realize by the L1 message of the HS-SCCH order with new or a kind of new type.Can on anchor carrier or subcarrier, transmit new HS-SCCH order or L1 message.Once receive this signal from network, this WTRU is just allowed to for example, start or stop to monitor subcarrier based on HS-SCCH order or L1 message (, activate for the subcarrier of " 1 " and for the subcarrier deexcitation of " 0 ").
Alternatively, once inactivity timer expires, this WTRU just can automatically stop monitoring subcarrier (that is, HS-SCCH and/or HS-DPSCH on subcarrier).More specifically, if in assisted cell, or alternatively in grappling and assisted cell, during the time quantum of configuration, do not receive down link data, this WTRU just can be forbidden the supervision on assisted cell.
This network can send HS-SCCH order or L1 signal to WTRU with the activation of indication subcarrier.This can be by using the L1 message of new HS-SCCH order or new type to realize in anchor carrier.Alternatively, if receive downlink traffic, this WTRU can automatically allow to monitor this subcarrier.Alternatively, start and monitor that the standard of subcarrier can depend on type of service or the data volume receiving.Once receive this signal from network, this WTRU just can be used configuration identical when receiving before deexcitation order to start to monitor subcarrier, or stops monitoring subcarrier.Especially, the DRX state for subcarrier can be restored to its state before receiving deexcitation order.
Alternatively, once activate or reactivate this subcarrier, the DRX of subcarrier can be disabled (or being alternatively activated) always always.Alternatively, when activating or reactivating, can configure by more high-rise signaling the DRX state of subcarrier.
On the other hand, when activating or reactivating subcarrier, this WTRU can bring into use and the same DRX pattern in grappling community (align or interlock).For example, if grappling community has the DRX of activation when activating assisted cell, this WTRU also can initiate DRX with identical receiving mode.If grappling community is in CRX, this subcarrier also can be in CRX.
This subcarrier activates and deexcitation also can be considered to two (or a plurality of) DRX schemes.The first DRX cycle comprises the DRX pattern that is applied to two kinds of carrier waves, wherein used an above execution mode of application, and the second DRX cycle comprises forbidding subcarrier, and continues DRX pattern or the continuous reception in anchor carrier.This is 2 stage D RX mechanism.First stage comprises from CRX to DRX, and second stage comprises from DRX to inertia.Conversion between DRX cycle can be depended on or its combination in following option:
(1) inactivity timer;
(2) HS-SCCH order as above or L1 signaling;
(3) RRC signaling;
(4) receiving downlink business (that is, HS-SCCH or HS-DPSCH) in a carrier wave; And
(5) in a carrier wave, receive the downlink traffic (that is, HS-SCCH or HS-DPSCH) of the schedule information on other carrier wave of indication.
Once this WTRU is in the second DRX cycle, if receive HS-SCCH order, if or receive downlink traffic, this WTRU just can be transitioned into the first DRX cycle (two carrier waves are all in DRX) here.Alternatively, this WTRU can directly be transformed into continuous transmission from the second DRX cycle.
On the other hand, this WTRU can be forbidden and start and monitor downlink anchor cell channel (that is, HS-SCCH and/or HS-DPSCH), and utilizes the DRX cycle of configuration to intercept assisted cell, or intercepts the continuous reception in assisted cell.Startup as above/forbidding monitors that the option of assisted cell also can be applicable to this replaceable execution mode.
Following discloses for improving the execution mode of economize on electricity on WTRU.Define one group of new rule and signaling, thereby for the WTRU in DC-HSDPA pattern, carried out quick active and the deexcitation of DRX/DTX.Each downlink carrier be can be respectively and activation and deexcitation carried out.This can send to WTRU to realize with signal activation/deactivation order by explicitly in each HS-SCCH order of each carrier wave.The result that this flexibility causes is extra power consumption, signaling load and on down link, uses more code space.
According to an execution mode, two DTX/DRX states with the WTRU of DC-HSDPA ability are to be defined by the DRX state (activity or inertia) of state, grappling and the subcarrier of subcarrier (activity or inertia) and the combination of the DTX state (activity or inertia) on uplink carrier.The WTRU with DC-HSDPA ability can be in a plurality of pairs of DTX/DRX states.Some conversion from two DTX/DRX states to another pair of DTX/DRX state may be than other more general.Thereby the signaling cost relevant to these will be reduced to minimum.
Provide following signaling mechanism with regular set to reduce the signaling load associated with general state photograph.They can be used in combination with any order or with any.
Rule 1: when subcarrier is during in active state, and when going up explicitly activation DRX in anchor carrier (via conventional version 7HS-SCCH order), DRX is implicitly activated on subcarrier.This rule allows to reduce the number of HS-SCCH order, thereby makes in the DRX of WTRU in two carrier waves in the low downlink activity shape cycle.
Rule 2: for example, once explicitly activates subcarrier (, via HS-SCCH order), implicitly carry out the deexcitation of DRX on grappling and subcarrier.Alternatively, in UL anchor carrier, (and washability ground is on UL subcarrier, if present) also implicitly carries out deexcitation DTX.Although this process can realize via a plurality of HS-SCCH orders, this new rule allows network in high downlink periods of activity, promptly WTRU to be turned to complete state of activation.
Rule 3: for example, when explicitly is carried out deexcitation subcarrier (, using HS-SCCH order), implicitly start DRX in anchor carrier.Alternatively, in UL anchor carrier, also implicitly start DTX.This rule allows network, in low periods of activity, WTRU is moved to battery save mode quickly.
Rule 4: for example, when the forbidding DRX of explicitly on subcarrier (, via HS-SCCH order), the disabled DRX of implicit expression in anchor carrier.Alternatively, if there is the 2nd UL carrier wave,, when the forbidding of explicitly on the 2nd UL carrier wave DTX, DTX is implicitly forbidden in UL anchor carrier.This rule allows network to go, in low periods of activity, WTRU is moved to battery save mode quickly.
How Fig. 9 makes for realizing the conversion of power rating from low to high with rule 2 using single subcarrier to activate with deexcitation order together with rule 3 if showing, vice versa.In Fig. 9, four kinds of states have been defined: state 1 (DRX of assisted cell activity, Liang Ge community is movable), state 2 (the DRX inertia of assisted cell activity, Liang Ge community), state 3 (DRX of assisted cell inertia, Liang Ge community is movable), and state 4 (the DRX inertia of assisted cell inertia, Liang Ge community).Once receive assisted cell activity command (step 902), this WTRU is just transformed into state 2 from state 3, and activates the DRX of assisted cell and deexcitation Liang Ge community.Once receive assisted cell deexcitation order (step 904), this WTRU is just transformed into state 2 from state 3, and carries out the DRX of deexcitation assisted cell and activation Liang Ge community.
Alternatively, can realize by explicit signaling some implicit rules in above implicit rule.For example, also can be by come implementation rule 2 and rule 3 by explicit signaling.A kind of mode that realizes this purpose is by using single HS-SCCH order by the reserved bit in conventional H S-SCCH Command field bit, thereby for activation and the deexcitation of assisted cell, and indicate respectively the activation of DRX and deexcitation (for grappling and subcarrier) and optional DTX (at UL ripple).
For example, the first bit of three HS-SCCH Command field bits can be used for indicating the DRX of grappling and assisted cell to activate and deexcitation, and the second bit of three HS-SCCH Command field bits can be used for indication activation and deexcitation DTX.For example, if the first bit is set to " 0 ", HS-SCCH order is the DRX deexcitation order of grappling community and assisted cell.If the first bit is set to " 1 ", HS-SCCH order is the DRX deexcitation order of grappling community and assisted cell.If the second bit is set to " 0 ", HS-SCCH order is DTX deexcitation order.If the second bit is set to " 1 ", HS-SCCH order is DTX activation command.If there is auxiliary UL carrier wave, DTX also can be applied to grappling uplink carrier and auxiliary uplink carrier.
In DC-HSDPA, must give two CQIs of WTRU (CQI) feedback cycle value: one for grappling community, and another is for assisted cell.Network can offer WTRU via RRC signaling explicitly by these values: one for anchor carrier (k represents by variable), and one for subcarrier (by variable k
srepresent).The speed that this allows CQI report to be adjusted by network, for example, be optimized with respect to different DRX cycles.
According to an execution mode, the CQI feedback cycle duration of subcarrier can implicitly be determined by WTRU.The CQI feedback cycle of subcarrier can (that is, k identical with the CQI feedback cycle of anchor carrier
s=k).Alternatively, for the DRX cycle of subcarrier, be the situation doubly of factor (M) of the DRX cycle of anchor carrier, can provide by this factor being multiplied by the CQI feedback cycle of anchor carrier CQI feedback cycle (that is, the k of subcarrier
s=M * k).Can in stipulations, with signal transmission or pre-configured this, be worth M (for example, M=2).This method can merge with above disclosed other execution mode (for example, time migration CQI report), to realize maximum flexibility.
WTRU behavior when via described HS-SCCH order activation/deactivation assisted cell has been described.Once via HS-SCCH command execution deexcitation assisted cell, this WTRU just can refresh the HARQ buffer being associated with assisted cell, and/or order medium access control (MAC) entity, the HARQ transmission (when reactivating assisted cell) that the next one of the HARQ process of each configuration being associated with assisted cell receives should be considered to the first transmission.
Exist some methods to carry out above behavior.In one approach, once receive the deexcitation order of assisted cell, this physical layer just indicates this assisted cell to be deactivated to rrc layer.Subsequently, this rrc layer can be ordered MAC layer, and the next HARQ transmission of the HARQ process of all configurations that are associated with assisted cell will be considered to a HARQ transmission.The HARQ buffer that this rrc layer can also order MAC layer to refresh to be associated with assisted cell.
